h1. OsmoCBC
This is the upcoming Osmocom Cell Broadcast Centre.
h2. Introduction
You can find more information about Cell Broadcast in general at [[cellular-infrastructure:Cell_Broadcast]] and [[cellular-infrastructure:Service_Area_Broadcast]], as well as [[cellular-infrastructure:Emergency_Warning]] and [[cellular-infrastructure:Public_Warning_System]]. The pages include pointers to the relevant specifications.
h2. Position in the network
The below graph shows the CBC in the network.
{{graphviz_link()
digraph G {

CBC -> RNC [label="SABP", style="dashed"];

}
}}
As can be seen, the CBC receives messages from third-party applications (called CBEs). It then routes/distributes/forwards those messages over the respective radio access technology specific method.
h2. History
OsmoCBC was originally developed in 2019 under a so-called "prototype fund":https://prototypefund.de/ grant of the German Federal Ministry of Education and Research. FIXME.
In August 2022, osmo-cbc was extended with support for LTE/4G by introducing the SBcAP interface, under a "grant of the NLnet foundation":https://nlnet.nl/project/OsmoCBC/ {{include(cellular-infrastructure:MacroBinaryPackages)}}
